Music Synthesized From The Game Of Life

gameoflife_synth

[vtol] has built a very elaborate system of electronic sound machines, which can be patched together in various ways in order to create all sorts of sounds and sound effects. The modules range from simple noise synthesizers to pitch shifters, sequencers, and effects processors. The most recent addition to his synthesizer system is a matrix sequencer named 2112, which focuses on generating random sounds from a very familiar mechanism.

The sequencer simulates Conway’s Game of Life, representing the colony movements in beeps and buzzes, creating a nearly infinite array of random sound effects. Using firmware from the Game of Life board by Ladyada, the sequencer generates different sound patterns based upon the number of colonies on the board. The output varies according to the shapes and proximity of the organisms to one another. Since it is part of his already modular system, the 2112 board can be combined with any number of his other sound generators and effects machines to make all sorts of circuit bent music.

Needs More LEDs, EMSL Biggified Conway’s Game Of Life

Evil Mad Scientist Laboratories has proven bigger is better with their colossal LED table running Conway’s Game of Life. At the heart of the system is 44 ATmega164Ps controlling 352 LEDs on a 32×44 inch table; and to make it interactive IR LEDs detect the presence of objects.

The display is set up as an exhibit at the San Jose Museum of Art in tribute to [Leo Villareal]. To see a demo, catch a video after the divide.

LED Life And Charlieplexing


Yesterday, we featured [Andrew]’s orientation aware camera. We want to highlight another one of his projects: LED Life. It’s a 6×5 LED matrix playing Conway’s Game of Life. He used the low power MSP430 like our e-paper clock. The best part of the writeup is his explanation of how Charlieplexing works. Microcontroller GPIO pins generally have three possible states: output high, output low, and input. This combined with the directional nature LEDs and some creative wiring means you can run a large matrix of individually addressable LEDs with just a few IO pins. Instead of just flipping the IO pins on and off you change their assigned state. Have a look at [Andrew]’s site for some great illustrations of how the system works. A video of his LED Life board is embedded below. Continue reading “LED Life And Charlieplexing”
